Why breathability depends upon water repellency…
Breathable waterproof garments are most likely to get sweaty and wet inside when used in damp or wet conditions. If the outer fabric absorbs water, the garment can lose up to 70% of its breathability. Therefore, the Durable Water Repellency (DWR) on the outer fabric of your jacket must be maintained to ensure comfort. It will eventually wear off and need to be renewed with Nikwax TX.Direct®.
Waterproof clothing needs to be breathable…
When we work hard, we sweat. The evaporation of sweat cools us down and keeps us comfortable. But, when it rains we want to avoid getting wet, so we put on waterproof outerwear to keep us dry. The waterproof fabric must allow moisture vapour to pass through it, or 'breathe'; otherwise our sweat cannot evaporate, causing us to overheat and get wet from condensation.
Additionally, if the outer fabric of your garment absorbs water and ‘wets out’ its breathability will be reduced, causing you to feel clammy and wet.
Use Tech Wash and TX.Direct when your waterproof clothing soaks up water
Your raingear could be soaking up water just because it is dirty. Use Nikwax Tech Wash to clean it, and if it is fairly new, or recently re-waterproofed, the Durable Water Repellency (DWR) will be revitalised just from cleaning. But, once the garment has been thoroughly worn, you will need to add DWR, using Nikwax TX.Direct, always cleaning first with Nikwax Tech Wash.
Cleaning properly can be as important as waterproofing…
Using the right cleaning product is as important as using the right waterproofing product. Conventional detergents leave behind a thin water-absorbent film on materials, which masks their Durable Water Repellency (DWR). Therefore, always clean your waterproof garments with Nikwax Tech Wash. Remember that dirt itself works against DWR, so regular cleaning will enhance performance.
